 //  See http://www.boost.org for most recent version including documentation.
 
 //  Revision History
+//  02 Apr 01  Removed BOOST_NO_LIMITS workarounds and included 
+//             <boost/limits.hpp> instead (the workaround did not 
+//             actually compile when BOOST_NO_LIMITS was defined in 
+//             any case, so we loose nothing). (John Maddock)
 //  21 Jan 01  Undid a bug I introduced yesterday. numeric_cast<> never
 //             worked with stock GCC; trying to get it to do that broke
 //             vc-stlport.
